Pat the peeled and deveined shrimp dry with paper towels. In a medium bowl, combine all-purpose flour, paprika, cayenne pepper, salt, and pepper. Toss the shrimp in the seasoned flour mixture until well coated.

In a large skillet, heat the unsalted butter and olive oil over medium heat until melted. Add the minced garlic and sauté for about 30 seconds, stirring continuously.

Carefully add the seasoned shrimp to the skillet in a single layer. Sauté for about 2 minutes or until they turn pinkish on one side, then flip and cook for another 2 minutes.

Remove the skillet from heat. Squeeze fresh lemon juice over the shrimp and toss gently. Sprinkle with chopped parsley if desired.

Transfer the Garlic Shrimp to a serving platter. Drizzle the garlic butter sauce over the top and serve immediately.
